Iran leader tweets photos of Obama holding a gun to his head

On Saturday, Iran's supreme religious leader Ayatollah Khamenei tweeted this picture of what many say is a silhouetted President Obama holding a gun to his head.

The tweet is in response to Obama saying that the U.S. could still use military force should the recent nuclear deal with Tehran fall through.

Under the deal, Iran will be forced to limit its nuclear program in return for the lifting of billions of dollars of Western economic sanctions.

Ayatollah's picture reads, "We welcome no war, nor do we initiate any war, but if any war happens, the one who will emerge loser will be the aggressive and criminal U.S."
